Nostra Protocol Pauses Money Market After $3.5M Oracle Exploit

Key Facts

1Starknet lending protocol Nostra paused its money market following a manipulated price oracle exploit.

2The exploit allowed an account to borrow approximately $3.5 million against NSTR token collateral.

Amid ongoing security challenges in the decentralized finance sector, Nostra Protocol, operating on the Starknet network, has announced a temporary halt to its money market operations. This decision follows the detection of an exploit stemming from price oracle manipulation. According to reports, this vulnerability allowed an account to borrow approximately $3.5 million in assets against NSTR token collateral.

The incident highlights the systemic risks associated with price oracle dependencies in lending protocols, where manipulated collateral values enabled the attacker to withdraw liquidity beyond authorized limits. This proactive measure by Nostra Finance aims to protect remaining liquidity and prevent further user losses, amid concerns regarding the impact of such exploits on trader trust within the broader Starknet ecosystem.

Based on available market data, updated price levels for the NSTR token are currently unavailable (close September 18, 2026). Traders are closely monitoring official updates from the Nostra technical team regarding the resumption of operations or potential recovery plans. In the absence of immediate crypto-specific catalysts in the upcoming economic calendar, focus remains on the protocol's ability to remediate the security flaw.
